Abstract
In order to contribute to the survival of the waste final disposal site, this study constructed a cement recycling model of municipal solid waste incineration ash considering dechlorination. First, this research estimated reserving capacity of the ash of the existing cement plants taking into account the chemical composition of cement raw materials including incineration ash after dechlorination. Then, this article proposed a cement recycling model aiming at cost minimization in four patterns of dechlorination at incineration plants, existing cement plants, recycling port, and eco cement plant changing the reserving capacity. As a result of the model analysis, it was found that the relationship of the total cost is affected by the upper limit of the reserving capacity in the case of desalination processing at incineration plants, existing cement plants, and recycling port. In addition, the total cost can be reduced when using the eco cement plant compared to the other three patterns regardless of the upper limit of the reserving capacity.
